A supercapacity lithium ion battery cathode material, a preparation method therefor and an application thereof. The supercapacity lithium ion battery cathode material consists of a transition metal-containing lithium ion cathode material and carbon which is coated on the surface of the lithium ion cathode material. The transition metal on the surface of the lithium ion cathode material is coordinated with carbon by means of X&#x2014;C bonds to form transition metal-X&#x2014;C chemical bonds, such that carbon stably coats the surface of the cathode material, wherein C is SP3 hybridization and/or SP2 hybridization, and X is at least one selected from among N, O and S. The supercapacity lithium ion battery cathode material connects the lithium ion cathode material and the carbon by means of the transition metal-X&#x2014;C chemical bonds, and utilizes the transition metal-X&#x2014;C chemical bonds to repair boundary of lattices on the surface of the cathode material, such that an interface between the lithium ion cathode material and a carbon layer can be optimized, to form an interface that can store Li, thereby increasing the per gram capacity of the cathode material, and laying the foundation for preparing a supercapacity lithium ion battery.
